AVI captures are better quality?
Assuming good capture hardware/software is being used, whether the video is compressed now or later makes no difference. This situation reminds me of the Bugs Bunny cartoon where Daffy asks Elmer, “Would you like to shoot me now, or wait until you get home?” Seriously, there is no difference. Daffy was somehow fooled into believing one was better than the other, yet the outcome was the same. He had his bill blown off.
